When using a filter on a metric or dimension, the "is equal to" or "contains" criteria will not return the same results. Indeed, these two criteria may appear similar, but a subtlety differentiates them.
By applying the "contains" criterion, you will obtain visits exposed to more content than if you applied the "is equal to" criterion:
- The expression "contains" retrieves all the values containing at least the given string. For example by filtering the dimension Page :
We then observe 3 pages containing the character string 'home':
- The expression "is equal to" retrieves only the value corresponding precisely to the given string. For example by filtering the dimension Page :
We observe then only 1 page answering the strict criterion 'home':
